Conversely, ectopic expression of TPRA1 in bladder cancer UMUC3 cells, which showed less TPRA1 expression, rendered them more susceptible to OVM infection, and trans‐complementation of TPRA1 in 22Rv1ΔTPRA1 cells fully restored OVM infectivity (Figure 1F and Figure S3B, Supporting Information). The gene discussed is TPRA1; the disease is urinary bladder cancer.
